The Science of Sunglasses: Protecting Our Eyes and Making a Fashion Statement
For centuries, people have chosen to put on sunglasses for a myriad of reasons, from protection against sunlight to a fashion statement. But did you know that science plays a role in crafting our precious shades? In this article, we’ll explore the science of sunglasses and how it can be used to protect our eyes as well as make a bold fashion statement.
What Are Sunglasses and Why Do We Wear Them?
Sunglasses are a form of protective eyewear that are designed to protect eyes from excessive exposure to ultraviolet (UV) light. They are typically made with a tinted lens and a frame that fits comfortably against the wearer’s face. The purpose of sunglasses is to provide the wearer with comfort from bright sunlight, glare, and UV exposure.
Lenses and Materials Used
When it comes to the lenses used in sunglasses, there are a variety of materials used to provide maximum protection and a comfortably feel. Polycarbonate lenses are most commonly used because they are lightweight, scratch-resistant, and provide 100 percent UV protection. Other materials used to make sunglasses lenses include glass, CR-39 plastic, Trivex, polarised, and photochromic.
UV Protection
The primary function of sunglasses is to provide the wearer with UV protection. Too much exposure to the sun’s UV rays has been known to cause sunburns and even skin cancer. Wearing sunglasses with fully blockable UVR lenses can protect your eyes from the harmful UV rays. Additionally, some sunglasses contain anti-reflective coatings which aid in reducing the amount of glare from roads, snow, and water.
Protecting Against Blue Light
Sunglasses can also be used to protect your eyes from blue light — a high-energy light found in sunlight. While some blue light exposure can be beneficial for the body, too much can have a detrimental effect on eyes. Studies have shown that blue light increases the risk of cataracts and age-related macular degeneration. Wearing sunglasses with blue-light filtering lenses is a great way to protect your eyes.
Fashion Statement
While sunglass are designed to protect eyes from the sun’s harmful ultraviolet rays, they also make a great fashion statement. The style and design of sunglasses can be used to express individual style and personality. In recent years, the popularity of aviator, round, and oversized frames have been at the forefront of sunglass fashion trends.
The Different Types of Sunglasses
When it comes to different types of sunglasses, there are many design choices to choose from. Aviator sunglasses are popular for making a bold statement and often contain metal frames with dark lenses. Wayfarer sunglasses, on the other hand, feature plastic frames with darker, solid-colored lenses. In addition, there are many other popular designs ranging from cat eyes, round frames, and rimless ones.
The science of sunglasses is an engaging topic that can provide people with a clear understanding of how to protect their eyes from the sun’s harmful UV rays. Not only do sunglasses provide needed protection, but they also make a bold fashion statement. By selecting the right lenses and design for your needs, you can find the perfect pair to make a statement and keep your eyes safe.
